magnetic exercise bike resistance?

Louise c · Yahoo User

i have a magnetic exercise bike,the the tension control for the resistance works fine but it only goes up to 8 and its hardly any different from having it on 1 2 3 4 5 6 or 7 theres not enough resistance and isnt at all an effort to cycle and work up a sweat,is there anything i can do to change this,thanks for your answersdo u think i will still burn as many calories as i would have havin the resistance was higher and harder to peddle or not?also i brought it from my sister inlaw so i didnt assemble the bike myself,so do u think there could be the possibility she didnt assemble the inside correctly or is this the way magnetics work....i know theyre meant to run smoother but surly this isnt enough resistance,or is it?
